Description
Technical field
The present invention relates to a kind of movable type hydraulic jacking device, be applied to the carrying of shipbuilding industry large-scale steel structure members inter process.
Background technology
At present, shipbuilding industry, for large-scale steel structure members inter process carrying landing, the general large-scale Special jack that all uses customization with hand barrow or the mode of transport by manually lifting, is transported to work-site with it, again by manually it being unloaded from hand barrow, be installed to the landing operation point, its many large-scale Special jacks are placed the horizontal adjustment of height, solve with the flitch bed hedgehopping in its bottom.Use this large-scale Special jack and finish the carrying landing of large-scale steel structure members inter process, exist carrying loaded down with trivial details, inefficiency is adjusted inconvenience, the drawback that labor strength is large.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of movable type hydraulic jacking device, to simplify the carrying landing of shipbuilding industry large-scale steel structure members inter process, improve the carrying work efficiency.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of movable type hydraulic jacking device, comprise vehicle frame, the hydraulic control device that is placed with jack on the described vehicle frame and is connected with jack, this jack comprises base, places hydraulic ram and piston on the base, is connected with the actuating device that drives cylinder body of hydraulic oil cylinder radial rotary certain angle between described vehicle frame and the hydraulic ram.
Described actuating device comprises the handle that axis body is fixedly connected on the rotating shaft on the cylinder body of hydraulic oil cylinder and captives joint with rotating shaft, and the two ends of described rotating shaft are fixedly connected on the vehicle frame by bearing and bearing seat.
Be connected with respectively symmetrically a connecting rod mechanism in the described rotating shaft, described connecting rod mechanism comprise first connecting rod, the second connecting rod that is located by connecting on the cylinder body of hydraulic oil cylinder and be connected to first connecting rod and second connecting rod between third connecting rod, the coupling end of described first connecting rod and third connecting rod is connected in the rotating shaft.
Described first connecting rod and second connecting rod equal in length, and both be arranged in parallel.
According to above technical scheme, can realize following beneficial effect:
1. the present invention is connected with the actuating device that can drive this hydraulic ram radial rotary at cylinder body of hydraulic oil cylinder, then when jack is not worked, can jack be lain in a horizontal plane on the vehicle frame by actuating device, make things convenient for the migration of jack, and when jack is worked, the vertical vehicle frame of jack can be placed, so that the landing of large-scale steel structure members is carried out, know thus, according to technical scheme of the present invention, in whole large-scale steel structure members inter process carrying landing process, jack and vehicle frame link together all the time, no longer separate, then can avoid a dead lift jack, save manpower work expenditure, reduce labor strength, thereby increase work efficiency;
2. actuating device of the present invention is a handle that is fixedly connected on the rotating shaft on the cylinder body of hydraulic oil cylinder and captives joint with rotating shaft, then can pass through turning handle, drive rotating shaft and do 90 ° of rotations, thereby so that hydraulic ram can realize in the migration process that level places on the vehicle frame or working process is vertically placed.
3. the present invention is symmetrical arranged a connecting rod mechanism at the rotating shaft two ends, thereby so that during rotatable handle, more easily drive hydraulic ram and do 90 ° of rotations, namely because first connecting rod and second connecting rod can be respectively around locating dowel pin and rotating shaft rotations, so when hydraulic ram is become upright position in the working process by the level attitude in the migration process, only need handle band hydraulic cylinder to turn an angle, then hydraulic ram itself can vertically land because of its deadweight, and automatically regulate horizontal high and low position, no longer need the people for moving and regulating, otherwise, after hydraulic ram turns an angle because of the backward rotation of rotating shaft, it also can level drop on the vehicle frame because of deadweight, need not carrying.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Explain technical scheme of the present invention below with reference to accompanying drawing.
As depicted in figs. 1 and 2, movable type hydraulic jacking device of the present invention, the vehicle frame 1 and the wheel 5 that comprise hand barrow, the hydraulic control device that is placed with jack and is connected with jack on the described vehicle frame 1, this jack comprises base 63, place hydraulic ram 61 and piston 62 on the base 63, be connected with the actuating device that drives hydraulic ram 61 cylinder body radial rotary certain angles between described vehicle frame 1 and the hydraulic ram 61, described actuating device comprises the handle 7 that axis body is fixedly connected on the rotating shaft 9 on hydraulic ram 61 cylinder bodies and captives joint with rotating shaft 9, the two ends of described rotating shaft 9 are fixedly connected on the vehicle frame 1 by bearing and bearing seat 10, described hydraulic control device comprises hydraulic oil pump motor 4, fluid control valve 3, hydraulic power unit 2 and high pressure fuel pipe 8, described high pressure fuel pipe 8 is connected between fluid control valve 3 and the hydraulic ram 61.
In addition, for making 61 rotations of handle 7 band hydraulic cylinders more easy, the present invention is connected with respectively a connecting rod mechanism symmetrically in rotating shaft 9, described connecting rod mechanism comprises the first connecting rod 11 that is located by connecting on hydraulic ram 61 cylinder bodies, second connecting rod 14 and be hinged on first connecting rod 11 and second connecting rod 14 between third connecting rod 12, both coupling ends of described first connecting rod 11 and third connecting rod 12 are connected in the rotating shaft 9, and first connecting rod 11 and second connecting rod 14 equal in length, and both be arranged in parallel, in addition, described first connecting rod 11, second connecting rod 14 is located by connecting on the hydraulic ram 61 by locating dowel pin, and second connecting rod 14 and third connecting rod 12 both carry out hinged being integral by pin 13, then during rotary handle 7, described first connecting rod 11, second connecting rod 14 and third connecting rod 12 all can be along with rotating, and in the whole rotary course, connecting rod mechanism is always a parallelogram.
When migration during hydraulic ram 61, for ease of movement, then hydraulic ram 61 levels are placed on the vehicle frame 1 of hand barrow and migrate; When hydraulic ram 61 is migrated to work-site, handle 7 is made clockwise direction to rotate, so that hydraulic ram 61 becomes the upright position by the level attitude in when migration, in addition, because the existence of connecting rod mechanism, then first connecting rod 11 and second connecting rod 14 can rotate around pin and rotating shaft 9 respectively, so when hydraulic ram 61 becomes the upright position by level attitude, when its by handle 7 with the radial rotary certain angle after, rely on its deadweight, hydraulic ram 61 meeting automatic rotatings are regulated horizontal high and low position simultaneously automatically vertically to land, and do not need the people for moving and regulating; When hydraulic ram 61 finishes work at present, handle 7 is made counterclockwise to rotate, so that this hydraulic ram 61 becomes the level attitude that lies on the hand barrow vehicle frame 1 after rotating 90 ° by the upright position in when work, thereby can be convenient to it is migrated to next work place.
